You're still confused, or intentionally ignoring what you're being told. It is impossible to make a .30-06 that has the same velocity with the same bullet as a .308 with the same weight and recoil. If the velocity is the same, the .30-06 will either have more recoil, or be heavier (to keep the recoil the same).
That is correct and agrees with what I wrote. That said, some .30-06 rifles are heavier and some are lighter than available .308 rifles. Felt recoil is not a simple matter of cartridge choice.
Even at maximum loads the .30-06 is has recoil readily managed by most shooters. If it didn’t the .30-06 would have fallen from favor decades ago.

That is the simple consequence of using a less efficient cartridge. There's no way around it - simple physics at work.
What you fail to understand is that “efficiency” depends on what is being measured. The .30-06 can do what the .308 Win can do but do it at lower pressures for longer barrel and brass life. It can also easily surpass the .308, reaching territory the .308 Win cannot. Want to push a 110g bullet to 3500fps or a 180g bullet to 2800fps? Don’t reach for a .308. It’s efficiency in the regions it can’t reach is a goose egg.

Oh, any you're not getting an extra 100y of effective range unless you're loading overpressure .30-06 or underpressure .308. The difference in velocity is much smaller than that.
Once again you are wrong. Using Hodgdon load data, the .30-06 pushes a 180g bullet to 2840fps with 56,700 PSI while a .308 tops out at 2683fps at 58,200 PSI. Assuming a Nosler AccuBond (B.C. 507) the .30-06 retains 2000fpe to 445 yards while the .308 manages only 335 yards. By my count that gives the .30-06 a 110 yard advantage with no overpressure needed.
In any case, I have no problem loading the .30-06 to .308 pressures in my Remington 700 and Ruger M77/MKII rifles any more than I have a problem loading my .257 Roberts to SAAMI +P pressures. If the .30-06 was introduced today there is little doubt the pressure limit would match or exceed the .308 Win’s 62,000 PSI SAMMI MAP.

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.
